Roll Some Dice will roll any number of standard dice (d 6's) and optionally add or subtract a modifier from each dice. Alexa will then tell you the total of the rolls plus or minus the modifiers. For example, you might say 'Roll 3 dice plus 1' and Alexa will roll 3 d 6, getting, say, 3, 4, and 6, then add 1 to each roll, getting 4, 5, and 7, and will tell you the total, 16.
